也就是说,当底为第一个数,指数为第二个数时,用(int)(Math.log(x)/Math.log(base))是有问题的,又有人提出用近似值("epsilon")来减小误差:(int)(Math.log(x)/Math.log(2)+1e-10),这种方法也是可以的; 方法二: publicstaticintlog2(intn){ if(n <=0)throw new IllegalArgumentException(); ret...
指数函数：指数函数是y=a^x的形式，其中a是底数，x是指数。在calculate中，可以使用“^”符号进行指数运算。例如，2^3等于多少？对数函数：对数函数是y=log_a(x)的形式，在calculate中，可以通过输入"log(num, base)"来计算，其中num是你要求的数，base是你想用哪个底数计算。例如，log...
